MRBF Series Marine Rated Battery Fuse - Eaton Bussmann Series

The Eaton Bussmann MRBF-300 is a high-performance, space-saving circuit protection solution designed specifically for demanding DC power environments. With an increased voltage rating of 58V DC, this fuse is ideally suited for modern 48V battery systems as well as 12V and 24V configurations. The Marine Rated Battery Fuse (MRBF) architecture allows for high-current protection in the smallest possible footprint, mounting directly to battery terminals or specialized busbars to eliminate the need for additional fuse blocks and cabling.

Built to survive harsh conditions, the MRBF-300 is IP66 rated for moisture protection and ignition protected according to SAE J1171 standards, making it safe for installation in engine compartments and battery rooms where explosive gases may be present.
